IMPROVEMENT IN ATTACHMENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 110,810, dated January3, 1871.

To all whom it may concern:

Be it known that I, WILLIAM H. WHITE, of Baltimore, in the county ofBaltimore and State of Maryland,haveinvented anew andImproved CombinedGuide for Sewing-Machines; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawing, making a part of this specification, in whichFigure 1 represents the plate cut out to form the guide. the plate inmaking the guide. Fig. 3 represents the second bend in making the guide.Figs. 4, 5, and 6 represent cross-sections of the guide, taken on thelines 00 w, y 3/, and z 2, respectively, of Fig. 3.

The object of this invention is to combine, in one simple, practicableinstrument, devices which will fold, hem, and bind in many differentways, and to adapt such instrument at the same time to the manufactureof French folds in two, three, or more parts.

To accomplish this object I employ the device which I will now proceedmore particularly to describe.

In carrying out my invention I first cut from sheet metal, or otherequivalent material, a plate, A, of the form shown in Fig. 1, and nextbend the lateral edges or points inward, to form check-guides cc, asshown in Fig. 2. The plate receives a second bend along the dotted linesshown in Fig. 1, and a third and last bend along the centrallongitudinal line, to reduce it to the finished form exhibited in Fig.3.

The cross-sectional views shown in Figs. 4., 5, and 6 represent thepeculiar form of the scrolls or bent edges of the same, which proceedfrom a double curve to a simple U or V shape.

The location of the points or check-guides 0 e, or rather the curvegiven to the inner edges of the guide, is an important part of myinvention. Hitherto the edges of guides designed for analogous use havehad a double curve their whole length, which is objectionable, in viewof the liability of choking the passage at seams,

thereby stretching the bias binding-strip,

which, as is well known, has a tendency to contract or draw together thebound edge of the cloth after being stitched.

The U or V shaped end of the guide retains Fig. 2 represents the firstbend of the compressed form given to the fabric by the double scrolls,and also brings the hemmed edges into still closer contact-i. 0., intoshape for delivery to the presser-foot of the sewingmachine. Thiscompression of the folded edges is essential, since the presser-foottends to throw the upper hem from under the needle. The slits i t in theguide allow the escape of the folded or selvage edges of binding, whichare held in place or controlled by the hooks O O. The guide thus formedis soldered to the edge of a supporting-plate, B, as shown in Fig. 7 andadjustable hooks G are connected with it and plate B by means of aclasp, D.

The hooks are formed on the ends of the spring-plate, which is so bentthat they press against each other in the clasp D, so as, by friction,to remain immovable wherever set.

This is preferable to the old method of securing them by a set-screw.They extend through slots a in the edge of guide A, the hooks bendingdown into the channel of the guide-plate, as'seen in Fig. 7. These hooksare used for drawing the folded edge of the fabric in against the back,thereby lessening the size of the hems and bindings, and they can beadjusted at will to produce such effect to any desired degree. Thesehemmer-hooks, in conjunction with the double scroll-guide A, arearranged or particularly adapted to produce what isknown as the Frenchfold?- This fold is an article of dress-trimming which is made bycutting strips from cloth on a bias edge, and folding or turning overeach edge of the same, and again folding it upon itself in such a waythat one of the turned edges shall project beyond the other.

By adjusting one of the hemmer-hooks C C so as to project beyond theother, a bias strip passed through the guide will appear as a Frenchfold.

Fig. 9 represents an attachment, E, intended for lining or stuffing abias binding or fold, or for holding a braid in place when being applied to the edge of a fabric. The lining passes through the opening mand the strip to form the outside through the opening a.

The position of attachment E with relation to the guide A is shown inFig. 3. It performs its work in a remarkably neat and effective manner.

Fig. 8 shows an attachment, F, (which can,

be seen in place, connected with the guide A, in Fig. 7,) designed to beused as a partition between the scroll-hemmers, so one can be usedindependently of the other.

In practical operation the fabric to be hemmed rests against thedividing or partition plate, which acts as a presser at the small end ofthe guide, to hold the hem firmly in place. It is attached to the guideby a hook or other suitable means.

For convenience I prefer to connect the devices E and F, as illustratedin Figs. 7 and 8.

Having thus described my inventionnvhat I claim as new, and desire tosecure by Letters Patent, is-- 1. The combination of the adjustablehemmer-hooks O O with the double hemmer-guide A, for the purposes and inthe manner substantially as specified.

WM. H. WHITE.
